3 Claims. (ones- 14) This invention relates to a machine for treating material and particularly to wire drawing by the continuous method wherein the material is drawn through a die by means of a rotating drum and thence passed on toa succession of dies and drums until the wire is drawn to the desired diameter. I

One of the important aims of this invention is the provision of a material treating machine having a part for supporting a number of elements, which part is of unitary character andformed to be machined-accurately and quickly. The invention resides in several combinations and arrangements of parts, which shall be hereinafter described, and are speoificallypointed out in the annexed claims, reference being had to the accompanying drawings wherein:

Fig. 1 is a fragmentary side elevational viewer 1 the wire drawing machine, embodying my invention, having. a portion thereof broken away in order to show. certain of the parts. I

Fig. 2 is an inverted plan view of the machine having a portion of the bearing structure broken away to show the method of journalling' the drive shaft, and also showing a portionof the shaft,

bearing structure and housing, broken away to reveal the base upon which the shaft and associated structure are supported. I

Fig. 3 is a plan view of thewire drawing chine.

Fig. 4 is an enlarged sectional View of the machine taken on.1ine IVIV of Fig. 3 and 'also partially shows, in diagrammatical form, the

manner in which the machine is to be lubricated and cooled. I

Fig. 5 is a fragmentary inverted plan view of a modified form of the shaft and bearing structure, parts being broken same; and i Fig. 6 is a fragmentary view of another modified form of the shaft and bearing. structure, showing a portion thereof in section.-

In the type of machine as employed by applicant, it is necessary that the speed of drawing the wire, and hence, the rotation of the blocks, be increased as the wire is passed through successive dies. This speed must be in proportion to the elongation of the wire, and one of the objects of applicants inventiomis to attain this mode of operation with a minimum of apparatus and in a highly eflicient manner.

One of the difficulties encounteredin the design of such apparatus has been the provision of gear structure which may be suitably driven from a single prime mover, since the forces required to rotate the drums are relatively large,"-it is necessary the structure employed be rigidly mounted in such manner that gear trains and the like, are held in tight engagement. To acconiplish this end the blocks are preferablymounted on a long, heavy, reinforced, unitary bed, and are adapted to be rotated by gears which are preferably driven by pinions or the like mounted on a longshaft, which is in turn, rigidly securedito the aforesaid base. I 7 It has been found desirable bythe applicant,

' that the gear structure of each successi e block be such that the gears are of substantially the same diameter or dimensions, whereby the same may be associated in such manner that a minimum amount of displacement ofthe parts will occur. Further, it is desirable to employ structure whereinthe length of the gear train is reduced toa minimum.

A machine constructed to achieve these ends is shown in the accompanying drawings,'-wherein unitary frame in provides for the rotative sup port of a series of drums or blocks l2. As shown in Figs. 1 and 4, each block is provided :withgan extension It, The wire to be drawn (not shown in thedrawings), is initially pulled across guide pulley l6 and through die 18 where it is wound away to clearly reveal the on block i2, passing upwardly around extension M, and thence throughfeyelet I9'of guide 20. The wire then passesthrough pulley 24, which'is held in place by support 22; from thispulley 24 the Wire is drawn across guidepulley l6 and die I8 toward the next succeeding drum l2.

As best shown in Fig. 2, the prime mover is a motor 26 which is interconnected by means of drive connection 28, with one end of a segmented shaft 3!]. Shaft 30 has a worm gear 32 mounted upon each segment thereof.

Shaft it extends along the length of frame Ill and is positioned so that worms 32 will operably engage gears 34. Gears 34 are adapted to rotate blocks l2 in the conventional manner. The segmented shaft 38 issupported at intervals by means of bearings 38 which the journalled in collars 3'5. These collars 36 are supported by frame It! upon bases 42.

The segments of shaft 30 are keyed at the ends thereof and are adapted to be joined by means of keyed sleeves 4!] which are placed over the ends of said shaft 30.

SleevesAfl are slightly loose-fitting on shaft 30 whereby flexibility is imparted to the shaft which facilitates assembly and reduces friction between the bearings and the shaft, thereby reducing the power required to operate the machine.

Frame It is machined from a unitary piece of metal.

The edges and bases 42 on the lower side thereof are machined together. After said edges and bases 42 have been properly planed, the entire top surface of frame Ill is machined to be parallel with respect to the underside of the frame. This procedure insures that the collars 35 may be positioned whereby to hold the shaft and gears supported therein in proper operative relationship with blocks I2.

As shown in Fig. 4, blocks [2 are supported upon a spindle 46. This spindle 4l5 is journ'a'lled I by means of roller bearingsffjiil and is held in operative position by the interactionof shoulder -.r.esp ctively. As .previously -mentioned, the ma- ;chinedsurfaceson-the top ofrframe til gare trued with .-respect .to -:.the gearing beneath wtne frame, and .in this manner, members 52 hold the =spindie \46,-and (hence, v gears 3d, .in ,propenoperative .rel ation withworm 32 -at;all=times. This feature further makes for quick interchangeability rof 1 the .blocks 42 when :desired. 2

..D1zip,-pan 54 extends :the length-and across .the underside of frame It and is 1-positioned im- .mediatelyabelow gears 32 and 34. :At' the lowest point of the drip .pan M .is affixed a trough 5E. I

Line .58 .is-thentconnected'with a branch whereby =oil .orpther liquid is distributed -by means of pipes .64 to points throughout the machine requiring lubrication'or-cooling.

Figs. 5 and6 'show a modification offkeyed shafbsegmentsM whereby'the same are adapted to engage the-end of the preceding segment in accept the ends of keyed segments 44. 0.

such manner that both segments may be rotatably supported by means of a single bearing structure 65.

- Fig. 5 shows a keyed collar 63 which is formed as an integral part of shaft segment 44 and is adapted to interlock with the keyed end 58 of the preceding segment 44.

Fig.6 shows a coupling l0 which is keyed to This coupling 10 is journalled within collars 3E mounted as previously shown in Fig. 2.

Y Having thus described the invention, what is claimed as new and desired to be secured by LettersPa'tent'is: 1. "In a =machine for drawing wire, a unitaryframe; "a series o'fsupporting members mounted on the frame; ab'lock and spindle assembly rovtatably carried'byeach member respectively; a,
